Adult osteomalacia

Bone-softening disorder caused by defective mineralization that develops in the context of the postpartum (puerperal) period, typically driven by calcium and vitamin D depletion from pregnancy and lactation.

Senile osteomalacia is age-related softening of bone in adults due to defective mineralization, classified under adult osteomalacia (M83) in ICD-10-CM Chapter 13.

Softening of bone in adults caused by impaired nutrient absorption in the gastrointestinal tract, including postsurgical malabsorption states, leading to deficient mineralization.

Softening of bone in adults caused by insufficient dietary intake of nutrients essential for bone mineralization, most commonly calcium or vitamin D from food sources rather than malabsorption or metabolic disease.

M83.4 identifies aluminum bone disease, a form of adult osteomalacia caused by aluminum accumulation in bone tissue, typically seen in patients with chronic renal failure who have been exposed to aluminum-containing phosphate binders or aluminum-contaminated dialysate.

Adult osteomalacia caused by a drug or medication other than aluminum-containing compounds, resulting in defective bone mineralization in a skeletally mature patient.

Billable code for adult osteomalacia that does not fit any of the more specific M83 subcategories — covering etiologies such as vitamin D deficiency with adult osteomalacia (avitaminosis D), craniotabes of unknown cause, and other documented but uncategorized causes of defective bone mineralization in patients aged 15 and older.

Adult osteomalacia with no documented etiology or subtype — use when the provider diagnosis of osteomalacia is confirmed but the underlying cause has not been specified in the medical record.
